A, "Banaraphyllum" ovatum Berry, 1937a holotype, USNM-201953 (illustrated in Berry, 1937a, plate IX, figure 1; see also Figure 27D and Tables 1, 2); B, Ziziphus chubutensis Berry, 1937a holotype, USNM-208529 (illustrated in Berry, 1937a, plate IX, figure 2; see also Figure 27C and Tables 1, 2); note the Cochlichnus trace fossils; C, MPEF-Pb-4129 (arrow, decurrent secondary veins); D, MPEF-Pb-2041 (exemplar, see also Figure 27B), note the naked basal vein (black arrow) and the margin feeding leaf damage (DT14, white arrow; see also Donovan et al., 2016); E, tooth detail from specimen in Figure 28D (arrow, an independent sinus vein); F, leaf base of MPEF-Pb-9119, note the naked basal vein (black arrow); G, MPEF-Pb-9120, with hole feeding leaf damage (DT05, arrow; see also Donovan et al., 2016). H-I, morphotype SA052 (Sapindaceae?), MPEF-Pb-2045 (exemplar, see also figure 27J). H, detail of the teeth and higher order venation (arrow, tooth venation forking at the sinus); I, complete (probable) leaflet. Single-color scale bars equal 10 mm; grid scales equal one millimeter (per rectangle).

Understand access before you commit
These curated guides explain access requirements, typical timelines, costs, and reuse considerations for widely used research datasets.
Allen Brain Atlas
Allen Brain Atlas is an Allen Institute collection of brain map atlases, datasets, APIs, and analysis tools covering mouse, human, and non-human primate brain resources.
Annotated Behaviour and Observability Dataset (ABODe)
ABODe is a University of Edinburgh DataShare dataset for behavior classification in group-housed mice using home-cage video, identities, bounding boxes, ground-plate positions, and annotator labels.
DANDI Archive for NWB datasets
DANDI is a BRAIN Initiative archive for publishing and sharing neurophysiology data, including electrophysiology, optophysiology, and behavioral data packaged as NWB and related standards.
International Brain Laboratory public data
The International Brain Laboratory public data releases expose standardized mouse decision-making experiments, including Neuropixels recordings, widefield calcium imaging, behavior, and session metadata accessed through the ONE API.
OpenNeuro
OpenNeuro is a free, open platform for sharing neuroimaging datasets, with public search, dataset pages, and download paths for web, S3, DataLad, and the OpenNeuro CLI.
